Re: Is there already a solution for mapping in Terminal (urxvt)?

For some reason, the message arrived garbled when sent in Latin1 so I'm
sending it again, but in UTF-8 this time.

To make Vim tell apart mappings, multibyte key codes, and successive
keypresses, see
:help 'timeout'
:help 'timeoutlen'
:help 'ttimeout'
:help 'ttimeoutlen'
:help 'showcmd'

I recommend using

:set timeout timeoutlen=5000 ttimeoutlen=100 showcmd

in your vimrc, but these values (where numbers are in milliseconds) are
what I'm comfortable with; they may vary according to your patience and
typing speed, and to the speed of your keyboard connection, so read the
help.

Note also that <Alt>+some-printable-key is stored internally as the
printable key OR 0x80, so ê (0xEA) is <Alt> + j (because j is 0x6A). See
also
:help 'esckeys'
:help :map-alt-keys
